Out-of-bounds read vulnerability in Apache Arrow Rust (`arrow` crate), from version 33.0.0 through to versions 57.3.1, 58.4.0, 59.3.1 and 60.0.0.

Improper validation of RunEndEncoded arrays in the ArrayData interface can allow reading data beyond the bounds of the child values array.

Users are recommended to upgrade to versions 60.1.0, 59.3.2, 58.4.1, 57.3.2 which fixes the issue.

RUSTSEC-2026-0442 — Apache Arrow Rust: Improper validation of RunEndEncoded arrays allows out of bounds reads

2026-11-05T12:51:04.105629+00:00

Affected: crates.io: arrow-data

Improper validation of RunEndEncoded arrays via `ArrayData::validate_values` can allow reading data beyond the bounds of the child values array when reading the last value via APIs such as `TypedRunArray::value`.

Patched versions now properly validate the contents of RunEndEncoded arrays to prevent allowing reading out of bounds of the specified array data.
